An assailant stabbed a policeman and was shot by police just outside Britain's parliament building in London on Wednesday (March 22) in what police described as a "terrorist incident". <br /> <br />Amid confusing scenes, it appeared the incident may have unfolded in several locations, including on the nearby Westminster bridge where eyewitnesses said a car had crashed into pedestrians. <br /> <br />Two people died in the incident, according to Sky News, but the total number of casualties was unclear. <br /> <br />The incident took place on the first anniversary of attacks by Islamist militants that killed 32 people in Brussels.
